Why Repair Your Chimney?
Repairing your chimney protects your home from some of the most common—and costly—roof problems. Worn mortar joints, cracked flaunching and tired lead flashings let water track into ceilings and loft timbers, causing damp, mould and rot; left alone, that moisture can spread and undermine the roof structure. A well-maintained stack also prevents smoke blowback and draught issues, reduces heat loss, and—on live flues—helps mitigate carbon monoxide risks by keeping the flue properly ventilated and sealed. Repointing, renewing flashings and securing or replacing damaged pots and cowls make the chimney stable in high winds, deter nesting birds and extend the life of the whole roof. In short: timely chimney repairs cost far less than fixing widespread water damage and keep your home safe, efficient and weather-tight.
Do I need repointing or a rebuild?
If damage is local and the bricks are sound, repointing plus lead renewal is usually enough. Loose, spalled or misaligned brickwork often calls for a partial rebuild.
Can you fix leaks without replacing the whole chimney leadwork?
Sometimes, if the lead is intact and only the chase or a local section has failed. We’ll show you photos and explain the best value option.
Should I cap a disused chimney?
Yes, with a vented cap so the flue can breathe. Fully sealing disused flues traps moisture and encourages damp.
Will you need scaffolding?
Often yes for safety and a better finish, especially on gables or tall stacks. We’ll confirm access in the quote.
Are you insured and do you guarantee work?
Yes, we are fully insured and provide written guarantees, length will vary by product and service.
